Xorg using abnormal high cpu in Debian wheezy with official Nvidia GeForce G105M driver of version 285.05

I re-installed my system with Debian Wheezy the other day. And then downloaded and installed the official Nvidia graphic driver for my GeForce G105M card. The driver version is 285.05.09 Certified published on 2011.10.05.

Setup SVN, https and Post-Commit Shell in Debian (Squeeze)

A different port other than 443 is needed, such as 19903. ( Wanna know why? See for more info)

So vim /etc/apache2/ports.conf, and add NameVirtualHost for port 19903:
Listen 19903

The name of virtual server can be arbitrary, such as 'test.svn',
So after everything is done, the URL for svn client to use will be https://test.svn:19903/

2. Make sure the 'Virtual Guest Additions' & also the Compiz package installed for the guest Debian.
